Assembly

Step 1 - Front Fork

If you do not feel comfortable assembling the bike yourself, Windhorse recommends taking your new bike to a bike shop for assembly and inspection. If you are willing to assemble the bike yourself, be sure to follow all instructions, properly adjust gears and brakes, and set tire pressure.

1. Locate the quick-release lever. Open the lever and remove the thumb nut, safety hook, cone spring (opposite the lever). Keeping the washer and other safety hook and cone spring in place on the lever side.
2. Line up the fork with the axle at the center of the wheel. Make sure there's a spacer between the fork and wheel on each side. Install safety hook, gasket, and nut in turn.
3. Tighten the nut onto the fork.
4. Install the front fork cover.

Note: When properly installed, the front wheel should be fully seated and centered in the dropouts of the front fork. The brake rotor should be in between the brake pads in the brake caliper, and the front fork nut should be fully and properly secured. Ensure the front wheel is properly secured before moving on to the next step.

Step 2 - Front Fender & Headlight

1. Take out the fender, remove the nut, washer and bolt at the top of the front fork.
2. Take out the headlights and screws (including 1xBolt, 1xWasher, and 1xNut). Slide the fender through the fork. Reattach the bolt, washers, fender, headlight, and nut (in that order) with a 5mm wrench.
3. Remove the nut, washer, and bolt at the bottom of the front fork. Slide the fender through the fork. Reattach the lower fender screws.
4. Plug in the headlight. Locate the two sides of the orange, three-pin headlight connector, carefully align the internal pins and notches and external arrows, then press directly together without twisting to fully seat the connection.

Step 3 - Stem

1. Loosen the screws to remove the front fork sleeve.
2. Take out the stem and insert it into the front frame.
3. Tighten the screws to fix the stem in place.
4. After making sure the stem is aligned with the direction of the tire, tighten the clamping screws below the stem to fix the direction.
5. Tighten the screws to fix the handlebar in place.
6. Cover the stem screw with stem screw plugs for protection.

Step 4 - Kickstand

1. Take out the kickstand and loosen the two screws on top.
2. Make sure the kickstand is aligned with the two holes in the frame.
3. Tighten the screws to fix the kickstand in place.

Step 5 - Rear Rack & Taillight

1. Loosen the four screws in the seat stay.
2. Align the rear rack with the seat stay and tighten the screws.
3. Take off the nuts on the taillight.
4. Assemble the taillight into the rear rack. Screw the nuts.
5. Use wrench to tighten the nuts.
6. For ride safety, secure the taillight cable to the seatstay with nylon cable ties.

Step 6 - Seat

For better pedaling, safety and overall riding comfort, positioning the seat at the right height is important. The rider's leg length is used to determine the seat's position. When you pedal, your hips should remain level and your legs should be almost fully extended at the bottom of the pedal stroke, but not over-extended.

To determine the right seat height, sit on the eBike with one pedal at its lowest point and place the ball of your foot on the pedal. Your leg should be almost fully extended (not locked out) with a slight bend at the knee.

1. Open the quick-release lever by swinging the lever open and outward fully.
2. Move the seat up and down by sliding the seatpost in or out of the seat tube. DO NOT raise the seatpost beyond the minimum insertion marking etched into the seatpost tube.
3. Adjust the seat and the head of the seat is parallel with the top tube.
4. Close the quick-release lever using your palm or finger.

Step 7 - Pedals

1. Locate the right-side/ left side pedal, which is marked "R," "L," should have an "R" "L," sticker attached.
2. Thread the right pedal onto the right crank gently by hand, turning clockwise. Then tighten pedal by wrench.
3. Thread the left pedal onto the left crank gently by hand, turning counter-clockwise. Then tighten pedal by wrench.
4. Check the chain alignment. Rotate the right pedal and crank toward the back of the bike as though pedaling backward. Watch the chain and ensure the chain runs through the drivetrain (the rear cog, chain tensioner, and around the front chain ring) smoothly.

Note: If the pedal/chain doesn't run smoothly or something seems misaligned, please contact Windhorse Support.

Start-up Procedure

After the bike has been properly assembled according to the assembly video, all components are secured correctly, a certified, reputable mechanic has checked the assembly, and you have read this entire manual, turn on the bike and select a pedal assist level following the steps below:

1. Familiarize yourself with the battery power positions. Turn on the battery first and cover the rubber case, ready for a ride.
2. Turn on the bike. With the battery locked in place. Locate the LCD display controls near the left handlebar grip. Hold down the (1) button for approximately 3 seconds until power is delivered to the LCD display and turn on.
3. Turn on the front light or tail light if needed or desired. Press the (5) button.
4. Select the desired level of pedal assistance (PAS) between level 1-3 using the + - buttons on the LCD display. Level 1 corresponds to the lowest level of pedal assistance, and level 3 corresponds to the highest level of pedal assistance. Level 0 indicates pedal assistance is inactive. Start in PAS level 0 or 1 and adjust from there.
5. Begin riding carefully. With the proper safety gear and rider knowledge, you may now operate your bike. On a flat surface, in a low gear (1 or 2), most riders should be able to begin pedaling the bike with pedal assist level 0 or 1. You may also use the throttle to accelerate and maintain your desired speed.
6. The throttle is used by slowly and carefully rotating the throttle backward toward the rider. Do not use the throttle unless you are on the bike.
7. Cruise mode activates after holding a steady speed for 10+ seconds. Braking cancels cruise control instantly.

Do not use the throttle while dismounted. Avoid accidental application of the throttle while dismounted; anytime you are moving the bike while dismounted, ensure the bike is powered off to prevent accidental application of the throttle.

Remove the Battery

1. Put the key into the lock, turn it to the left, which is the direction for unlocking.
2. When the battery is unlocked, it will pop down.
3. Prop up the battery with your left hand and then remove the battery with both hands.

When installing the battery, please slowly align the battery tube and place it into the battery tube. Then, gently press with your fingers to lock the battery. Ensure that the battery is securely attached to the bike mount.

Charge Your E-Bike

Before using the electric bike, you must fully charge the battery.

The battery can be charged off the bike. To remove the battery, turn the key to the left position (see the previous remove battery section for details).

Remove the rubber cover on the charging port on the opposite side of the battery from the key switch. Connect the DC output plug from the charger to the charging port on the side of the battery.

Plug the charger into a power outlet, charging should initiate and will be indicated by the LED charge status lights on the charger turning red. Once fully charged, the charging indicator light turning green. Unplug the charger from the wall outlet first and then remove the charger output plug from the battery charging port.

Daily Care and Maintenance

Cleaning and Storage

If you see stains on the bike body, wipe them off with a damp cloth. If the stains won't scrub off, put on some toothpaste, and brush them with a toothbrush, then wipe them off with a damp cloth.

Notes: Do not clean the bike with alcohol, gasoline, kerosene or other corrosive and volatile chemical solvents to prevent dire damage. Do not wash the bike with a high-pressure water spray. During cleaning, make sure that the bike is turned off, the charging cable is unplugged, and the rubber flap is closed as water leakage may result in electric shock or other major problems.

When the bike is not in use, keep it indoors where it is dry and cool. Do not put it outdoors for along time. Excessive sunlight, overheating and over cooling accelerate the battery pack's life span.

Battery Maintenance

1. Use original battery packs; use of other models or brands may bring about safety issues.
2. Do not touch the contacts. Do not dismantle or puncture the casing. Keep the contacts away from metal objects to prevent short circuit which may result in battery damage or even injuries and deaths.
3. Use original power adapter to avoid potential damage or fire.
4. Mishandling of used batteries may do tremendous harm to the environment. To protect the natural environment, please follow local regulations to properly dispose of used batteries.
5. After every use, fully charge the battery to prolong its life span.

Storage and Disposal

1. Please try to store the bike in a cool and dry place between 50-77 °F (10°C-25°C). In extreme humid environments, the interior of the bike may suffer condensation or even water accumulation, which may damage the battery rapidly. Devices are not intended for use at elevations greater than 2000m above sea level. Prolonged exposure to UV rays, rain and the elements may damage the enclosure materials; store indoors when not in use.
2. In daily use, try to avoid recharging the bike after completely exhausting the battery. If the battery is low, charge it as soon as possible.
3. Please charge the bike every other month to preserve the battery.

Recommended Service Intervals

Regular inspection and maintenance are key to ensure bikes from Windhorse function as intended, and to reduce wear and tear on their systems. Recommended service intervals are meant to be used as guidelines. Real-world wear and tear, and the need for service, will vary with conditions of use. Windhorse generally recommends inspections, service, and necessary replacements be performed at the time or mileage interval that comes first in the following table.

Safety Check

Pre-Ride Safety Checklist

Your cables, spokes, and chain will stretch after an initial break-in period of 50-100 mi (80-160 km), and bolted connections can loosen. Always have a certified, reputable bike mechanic perform a tune-up on your bike after your initial break-in period of 50-100 mi (80-160 km) (depending on riding conditions such as total weight, riding characteristics, and terrain). Regular inspections and tune-ups are particularly important for ensuring that your bike remains safe and fun to ride.

Tire Inflation and Replacement

The F2 employs 26"x1.95" rubber tires with inner tubes. The tires are designed for durability and safety for regular cycling activities and need to be checked before each use for proper inflation and condition. Proper inflation, care, and timely replacement will help ensure that your bike's operational characteristics will be maintained, and unsafe conditions avoided.

Windhorse recommends 45-60 PSI for the stock tires on the Windhorse. Always stay within the manufacturer's recommended air pressure range as listed on the tire sidewall.

It is critically important that proper air pressure is always maintained in pneumatic tires. Do not underinflate or overinflate your tires. Low pressure may result in loss of control, and overinflated tires may burst. Failure to always maintain the air pressure rating indicated on pneumatic tires may result in tire and/or wheel failure.

Inflate your tires from a regulated air source with an available pressure gauge. Inflating your tires from an unregulated air source could overinflate them, resulting in a burst tire.

Even tires equipped with built-in, flat-preventative tire liners, like those that come with bikes from Windhorse, can and do get flats from punctures, pinches, impact, and other causes. When tire wear becomes evident or a flat tire is discovered, tires and/or tubes must be replaced before operating the bike or injury to operators and/or damage to your bike from Windhorse could occur.

When changing a tire or tube, ensure that all air pressure has been removed from the inner tube prior to removing the tire from the rim. Failure to remove all air pressure from the inner tube could result in serious injury.

Using aftermarket tires or inner tubes, not provided by Windhorse may void your warranty, create an unsafe riding condition, or damage to your bike. If required by law, ensure replacement aftermarket tires have sufficient reflective sidewall striping.
